You will have to replace your rear end and fabricate new mounts if you want to replace the transmission with something other than stock.

here is what u need

of course you have to modify the tube front end and make new mounts but other than that you only need good skills

maybe you also need a great portion of patience

i replaced my tranny on my 39 buick to an th700 with Bentsens kit and it took me about 2 long days (i have the body of the frame)

good luck
